This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This review discusses the potential of P. polyphylla saponins to treat acne through antibacterial, anti-inflammatory, immunomodulatory, and antioxidant effects, noting that acne's complex pathogenesis makes this line of research promising for future studies.

This review highlights the important role of lymphatic vessels in skin regeneration and their interaction with skin stem cells, emphasizing recent research advancements and potential implications for managing skin diseases.

This report presents a case of a CKD patient who, after contracting COVID-19, experienced a rapid decline in kidney function, hair loss, and spontaneous wart remission, highlighting a need for further investigation into these unexpected outcomes.

This study observed that extracellular matrix scaffold membranes performed less effectively in wound healing for aged mice compared to younger ones, with senescent SPP1+ macrophages potentially hindering epidermal and fibroblast repair abilities.

In this chapter, researchers discuss how microRNAs (miRNAs) interact with vitamin D signaling, highlighting their emerging role as mediators in vitamin D-regulated disorders and their potential for developing miRNA-based clinical applications.

This study demonstrated a novel use of tape stripping on a human skin model to simulate the inflammation and barrier damage caused by dry razor shaving, highlighting potential shaving and skin-care formulations that may mitigate such damage.

This review evaluates the role of the nuclear receptor PPAR- in skin diseases, highlighting its regulation of inflammation, lipid metabolism, and immune response, and suggests that PPAR-agonists could be promising therapies for conditions like psoriasis and atopic dermatitis.

This study found that dissolving microneedle array patches containing mesoporous silica nanoparticles can deliver antigen-loaded nanoparticles into mice effectively, inducing strong immune responses similar to traditional subcutaneous injection.

This research reported that the FDA approved Litfulo® (ritlecitinib) as the first oral treatment for severe alopecia areata in adolescents over 12 years old, with 23% of treated patients showing significant hair regrowth in clinical trials compared to 1.6% with placebo.

In this review, researchers discussed the anti-inflammatory and immunomodulatory properties of metformin and hypothesized that its topical application could benefit those with alopecia areata, given its effects on immune pathways, hair regrowth, and autoimmune disease management.

In this review, researchers examined the link between COVID-19 and telogen effluvium, a hair loss condition, noting that increased stress, immune response, medications, and worsening of underlying diseases may contribute to this condition post-infection.

In this case report, a 39-year-old man with sudden whitening of scalp hair due to alopecia areata experienced total regrowth of pigmented hair after six months without systemic treatment.

This study identified core genes and pathways involved in androgenetic alopecia, finding that genes related to hair follicle development are down-regulated, while those linked to immune responses are up-regulated, highlighting potential therapeutic targets.

This study found that patients with alopecia areata had significantly lower frequencies of IL-10 producing CD19+CD24hiCD38hi regulatory B cells compared to healthy volunteers, suggesting a potential role for these cells in the autoimmune response seen in the condition.

This review discusses various types of hair loss associated with COVID-19 and vaccinations, highlighting acute telogen hair loss as the most common form, but reports no new clinical results.

In this study, researchers reported that conventional treatments for folliculitis decalvans, which include steroids and antibiotics, are often ineffective, with many patients experiencing frequent recurrences of this scarring scalp disorder.

This study suggests that autophagy is essential for regulating TLR3-mediated regenerative processes in human keratinocytes.

This study identified key genes and pathways involved in the growth and development of forest musk deer hair follicles, providing insights into molecular regulation and laying groundwork for future research on related diseases.

This study suggests that allergens like linalool found in personal care products may contribute to the pathobiology of frontal fibrosing alopecia by affecting immune responses and stem cell function in hair follicles.

This case report describes post-COVID-19 telogen effluvium in a 39-year-old patient, suggesting that COVID-19 may trigger significant hair loss as a late symptom.

Linalool in personal care products may worsen frontal fibrosing alopecia by damaging hair follicle stem cells and triggering harmful immune responses.

This study provides evidence that innate lymphoid cells-type 1 can induce alopecia areata in human hair follicles, challenging the view that it is solely a CD8+ T cell-driven autoimmune disease.

This review outlines the potential of mesenchymal stem cells and their derivatives as emerging therapies for atopic dermatitis, but reports no new clinical results; the authors highlight the need for further investigation.

This study concluded that combination therapies often yield better results for treating atrophic post-acne scars than single treatments.

This study found that Nubian ibex have developed genetic adaptations in response to their desert environment, including enhanced skin barrier, DNA repair, viral response, and metabolism of toxic compounds.

This review summarizes literature and experiences on the skin manifestations in COVID-19 patients, suggesting some may help identify asymptomatic cases, but it reports no new clinical results.

In this case report, the authors describe a patient with coronavirus disease where visible skin manifestations were the most prominent symptom.

This study found that type 2 immunity, especially involving ILC2 cells, helps maintain skin homeostasis by regulating the proliferation and community stability of hair follicle epithelial cells in the presence of Demodex mites.

This article presents cases of two patients experiencing excessive hair shedding 2 to 3 months after COVID-19 infection, highlighting a possible link to telogen effluvium.
